34-Key Layout using ZMK

🦀 Ferris Sweep	🪸 Urchin	Forager

This is my personal ZMK keymap shared across three different 34-key keyboards. It’s drawn using keymap-drawer and includes configurations for both dongle-based and dongleless setups.

Firmware Builds

Keyboards support two connection styles:

Dongle Setup

• <keyboard_name>_dongle → Flash to the dongle
• <keyboard_name>_left_peripheral → Flash to the left half
• <keyboard_name>_right → Flash to the right half

Dongleless Setup

• <keyboard_name>_left_central → Flash to the left half (acting as central)
• <keyboard_name>_right → Flash to the right half

Layout Philosophy

• The layout loosely follows QWERTY conventions — for example, the top row still houses numbers and common symbols.
• With only 34 keys, space is tight. I prioritize frequently used characters and modifiers close to the home row and thumbs (e.g., []{}_-|:, space, backspace, control, tab).
• Combos are used sparingly and intentionally to avoid accidental activations.

Key Features

• Home-row mods inspired by urob’s timeless layout
  • Tuned hold-tap behavior for reliable mod/tap distinction
• Combos for essentials like:
  • Enter, Escape
  • Cut / Copy / Paste
  • Mouse toggle
• Multi-layer design:
  • BASE: Standard QWERTY with mod-taps
  • SYMBOL: Symbols and punctuation (top-row behavior)
  • NAVIGATION_NUMBER: Vim-style navigation and number row
  • MSE: Mouse keys and pointer control
  • FUNC: Function keys, Bluetooth, keeb settings
